I have only seen one small pic of the clamshell. In hand it looks a little lighter - chestnut brown I would say. Like CoH the clamshell is a heavier duty leather of a different colour to the book - but the colour difference is more marked with this new deluxe edition. The book itself it bound in a mid-brown leather which is very soft, so we will have to handle this book carefully!The clamshell has a lift up shelf on a ribbon to make extracting the book a little easier, but I am unwilling to tug on it just in case it isn't 100% solid... Unlike CoH, the page corners have been rounded off to approximate the round corners of the binding.

Links to a few quick snaps below. Apologies for the quality. The colours are lightened a little by the flash.
